Abstract

The possibility of using a laser sensor and piezoelectric patches for vibration suppression on aircraft was demonstrated. The control technique significantly increased the damping ratio and reduced the steady-state vibration of a model wing in a low-speed wind tunnel. The performance could be improved by using actuators that have a large force and a filter with less phase lag. It was shown that the laser can operate in clouds, and darkness has no effect on laser.
